What are the best practices for handling image resources in PHP?

When handling image resources in PHP, it is important to properly manage memory usage and ensure efficient processing of images. One best practice is to use functions like imagecreatefromjpeg(), imagecreatefrompng(), or imagecreatefromgif() to create image resources from file paths. It is also recommended to free up memory by using imagedestroy() to release image resources when they are no longer needed.

// Example of creating an image resource from a JPEG file
$imagePath = 'example.jpg';
$imageResource = imagecreatefromjpeg($imagePath);

// Process the image resource here

// Free up memory by destroying the image resource
imagedestroy($imageResource);
